Keeping your Aadhaar-linked mobile number updated is essential for OTP verification, downloading Aadhaar, eKYC, and accessing multiple Aadhaar services. If your old mobile number is lost, inactive, or changed, you should update it as soon as possible to avoid service interruptions.
In this detailed guide, we will explain how to change Aadhaar card mobile number using the official UIDAI process and how to use the mAadhaar app for related services.
Why Aadhaar Mobile Number Update Is Important
Your Aadhaar-registered mobile number is used for:
-
OTP-based verification on UIDAI services
-
Downloading e-Aadhaar (PDF) from UIDAI
-
Locking/Unlocking Aadhaar biometrics
-
Updating address online (via document upload)
-
Aadhaar authentication for bank, SIM, and government services
-
Using mAadhaar features like QR scanning and profile access
If you don’t have access to your old number, you may fail OTP validation and face delays in services.
